She said texts sent by Eggleton were very "overt and upfront" in terms of her drug dealing.
Her lawyer, Harry Edward, said Eggleton was totally co-operative with police and "very forthright" with information.
The pre-sentence report showed she was remorseful and developed an insight into how bad the offending was not only to herself but to the wider community, Mr Edward said. He said that while in prison waiting to be sentenced Eggleton had completed numerous courses, including a drug and alcohol course.
Judge Cooper said intercepted communication showed Eggleton was involved in drug dealing almost daily while under surveillance. The pre-sentence report said she had been a user of methamphetamine for three years and had become addicted.
While she said the selling was to support that addiction, Judge Cooper said the level of commercialism went way beyond that. "It was a money-making venture you were engaged in virtually full-time."
He said that in a letter to the court Eggleton expressed her desire to turn her life around.
Mr Cooper said he also had a letter from her grandparents which spoke about how Eggleton was a high achiever with great potential before leaving home at 16. Her life went downhill from there after getting involved with the wrong company, her grandparents said.
He sentenced her to four years in prison on the six methamphetamine-related charges. On the remaining four charges, which related to other drugs, he sentenced her to one year in prison, to be served concurrently.
